Optimised configuration of sensors for fault tolerant control of an electro-magnetic suspension system [PDF]
, 2011 For any given system the number and location of sensors can affect the closed-loop performance as well as the reliability of the system. Hence, one problem in control system design is the selection of the sensors in some optimum sense that considers both
